I used to have an option to set the browser (Tonvid) part of SMTube to a dark theme - I kept my old profile handy, and just kept using it for all of my Linux OS installs. But, a month or so ago, an update caused the font size and theme to go back to default (small font & white background) - and with no option, I can find, to put things back to the way they were. My eyesight cannot handle the small/white combo; I have a condition which renders things quite painful and unreadable this way.
Please tell me how to get things back to a usable state for me. Version: 18.9.0
Thank you.
